The development concept for the WZ 12-8E and 12-3 fields is the MOPU and subsea flowlines tied in to an existing platform at the WZ 12-8W field and on to other existing infrastructure, said co-venturer Horizon Oil.

The MOPU will be leased in order to minimise capital expenditure.

The WZ 12-8E and WZ 12-3 discoveries contain about 11.1 million barrels of oil, and first production is targeted for January 2019.
